Mopro is an open-source toolkit for client-side ZK proving on mobile. It lets developers port Rust-based ZK circuits to iOS, Android, React Native, Flutter, and web/WASM with minimal effort.
What Mopro provides
- Cross-platform bindings generation via CLI (Swift, Kotlin, WASM, etc.)
- Support for Circom, Halo2, and Noir circuits
- Also suitable for other computation-intensive protocols like FHE in Rust crates
- Up to 20x faster proving compared to browser-based snarkjs
Session content
- Architecture overview: how FFIs enable cross-platform support
- Live demo: scaffold a ZK mobile app using
mopro-cliand generate a proof on a real device - Real-world usage: Anon Aadhaar, zkEmail, EZKL, Semaphore
